本文研究了一体化闭环供应链应对市场需求和成本双扰动的调整策略。根据不同的扰动条件,给出了相应的调整策略,并通过数值分析证明了文中结论的正确性。通过分析发现,突发事件对一体化闭环供应链造成了很大影响,使得整体利润下降,但是通过采用应对突发事件的调整策略,可以在一定程度上缓减突发事件带来的不良影响,减少对闭环供应链的损失。研究还发现:(1)当市场需求和生产成本同时沿同方向扰动时,两者之间存在着一种相互促进的作用,两者扰动的合力在一定程度上加大对系统的不良影响;当市场需求和生产成本同时发生相反方向扰动时,两者之间存在着一种相互抗衡和制约的作用,两者的合力在一定程度上削弱突发事件对系统的影响。(2)废旧品加工成本的扰动对闭环供应链的影响较小,当废旧品加工成本扰动较小时,废旧品的回收策略可以暂时保持不变。
This paper studies the integrated closed-loop supply chain to cope with market demand and cost adjustment strategy of double disturbance. According to different disturbance conditions, the corresponding adjustment strategy is given, and the correctness of the conclusion in the paper is proved by numerical analysis. Through the analysis, it is found that emergencies have a great impact on the integrated closed-loop supply chain, making the overall profit decline, but through the adoption of adjustment strategies to deal with emergencies, to a certain extent, mitigate the adverse effects of emergencies , Reducing the loss of closed-loop supply chain. The research also found that: (1) When the market demand and production cost perturb along the same direction at the same time, there exists a mutual promotion effect between the two. The resultant disturbance of both increases the bad influence on the system to a certain extent. When the market demand and production cost fluctuate in the opposite direction at the same time, there exists a mutual counterbalance and restriction between the two. The synergy between the two weakens the impact of the emergency on the system to a certain extent. (2) The disruption of the processing cost of scrapped products has less impact on the closed-loop supply chain. When the processing cost of scrapped products is less disturbed, the recycling strategy of scrapped products may remain unchanged temporarily.
